[RFC] convert a host address to a string

Can you be a little more specific?

I just checked the config.h file generated by configure on
x86_64-windows, and I found this:

    /* Define to 1 if the "%ll" format works to print long longs. */
    #define PRINTF_HAS_LONG_LONG 1

If this is wrong, we have yet another problem.
